We have a single valve tap with showerhead (pull-up type) in our kitchen. There is a thin rubber attachment in the middle of the tap that connects the tap head with the base part. That part broke and it is leaking there. I do not know what to do. Is there a way to fix it or should i have to replace the entire tap.

I am sorry if i wasn't clear with my description.I don't know the technical name for that part. I am here with attaching a picture of our tap model. I have marked the broken part there. Hope that helps you to understand my problem.
